Your Answer for Question 1:
(2^N)/2

Your Answer for Question 2:
A bus is a shared communication link that uses one set of wires to connect multiple subsystems so that they can communcate with each other.

Your Answer for Question 3:
y = a.a + a.b + a.not(b)

Since a.a = a, (idempotent law)
y = a + a.b + a.not(b)

Since a.b + a.not(b) = a.(b + not(b)), (distributive)
y = a + a.(b + not(b))

By complementarity, (b + not(b) = 1),
y = a + a.(1)

By Identity (a.1 = a)
y = a + a

Since a+a = a, (idempotent law)
y = a

Done!
